I'm leaning towards the striker but I heard its overclocking sucks! Has any of th recent bios improved anything?

The 0901 and 1002 BIOSes have fixed the voltage issue that was affecting overclocking. There's also a new revision coming out to address overclocking issues with Quad Core (just like EVGA and everyone else). As long as you don't try to stick four sticks of memory in it, you'll overclock just fine (my 4 dominators are going back and getting replaced with 2x2GB G.Skills - for sticks kills my OC)
